A rigid tank of volume 0.5 m' is initially evacuated. A tiny hole develops in the wall, and air from the surroundings at 1 bar, 21°C leaks in. Eventually, pressure in the tank reaches 1 bar. The process occurs slowly enough that heat transfer between the tank and the surroundings keeps the temperature of the air the tank constant at 21°C. Determine the amount of transfer, in kJ.
